GAS BURNER.

Application filed .Tune 23, 192e.

13e it linown that l', @intimes L. liliirsiinn, a citizen ot the lelinited Sete-s, residinl ut Schenectady, in the county oil' Schenectzrdy und State ot New York, have invented certain new nud useful lmprovements in Gas Burners, of which the ih'illowing is :i specification.

The present invention relates to gas burners and particularly to gas burners wherein the burner is arranged .to be adjusted autoniuiticully toward and away from the utensil to be heated as the gas is turned oil and on to decrease or increase the iieme. ln this connection, it is known that much better eiticiency is obtuined from n gas burner it' it is correctly adjusted in accordance with the height of the thune, but ordinarily `the burner is set tor average conditions and operates at poorer eflciency a good iden-l o'i the time, and particularly when the is turned partly oli' to give a. low thune.

The object o1" the present invention is to provide an improved arrangement for automatically ad]l usting a .gas burner toward and away 'from the utensil being; heet-ed es the flame is turned lower und higher, which arrangement is simple in structure, is easily applied to either new kor old stores., ,and is kcapable ot being manufactured ut a low cost. its will be pointed out more fully hereinafter, my improved construction can be applied to a standard type oil' Oes burner in a Very simple und easy nir-.nner und itis this Vlieutnre ot my invention which I regard as being n'very in'iportant one.

Alloc a ionsideruliion of what l believe to be novel and my invention, ettention is directed to the `following description und the claims nppended thereto.

top plate oit o gas stove provided with an opening` 5,; 6 indicates a burner disposed the gas supply pipe. Connected to the gas supply pipe lis u cock or vali/'e 8 `oit usual construction which supplies ges from the pipe 7 to the burner G. It comprises e valve body 9 `having a tapered seat or opening in which is located `the vulve member 10. At-

tached to member 10 for turning the Valve on and oit is a handle 11. In valve member 10 is an opening,` 12 which when the valve member is turned, is brought into line with the inlet nipple 1&3 and theoutlet nipple 14. linlet nipple 13 is connected to Agas supply pipe 7, and outlet nipple 141 is connected to the gas burner by u shortdischzirge nozzle 1l. Nozzle 15 tits rather loosely into ren opening 16 in the .end of the burner as is well understood. lAt 17 is the usual disk for adjusting the supply `of air to the burner through `the opening 18. The throw `of vthe valve is limited by the pin 19 which cooperates with the spaced stops 2Q. This valve `constructionis the construction found ,ordinerilyon gasstoves and es ,is welllrnownin connection with such rvalites, the member l10 is usually held on its seat 1in the body 9 by a spring` which surrounds an extension 21 on the `lower ,end ot member 10 and is Iheld between the .bottom oit Valve body E) und the head of a screw 22 4which .sceews into the bottom of -vnliie member .10. Ordinarily u washer 23 is provided under lthe head of the screw 22 to furnish s sent `for This :arrangement is used to l'icepthe vulve .tight on its sent and :it the seme time permit it to `turn .reudily and be selt adjusting on its seat.

The arrangements@ far described is that lfound inthe ordinary 4gas stove and is to be teken as .typical of any .gas stove struc* ture.

Nov, according `to my invention, l. provide a `support 241- on which the burner is pivotally mounted. ln the present instance the support is in the form ot' n trame hsving two purallelside pieces 25 connected by a liront cross ypiece V26. The reer ends ,ot side pieces 25 are bent downwardly to provide fingers 27 which tit loosely into openings 2 8 in a supporting strip 29. Support- .iiigstrip 29,extends alongnt the reur ofthe burner :md may be supported in any suit- Kto register with opening 5, and 7 indicates able manner at its two ends on the end frames of the stove. The burner has two projecting arms 30 provided with pivot pins 3l at their ends which extend through openings in side pieces 25 and receive cotter pins to hold the burner in place in the trame. Vith this arrangement it will be seen that when the front end of support 24 is raised, the same turning on support Q9 as a tulcrnm, the burner will be moved toward the top plate and that when such iront end is lowered the burner will be moved away 'from the top plate 5.

In connection with this burner supporting arrangement I then provide tor raising and lowering it a cam 33 or other equivalent means which is mounted on the valve member extension 2l. Cam 33 is formed on the periphery ot' a disc S4 at the center of which is a spacing sleeve Spacing sleeve 35 slips over the extension 2l and is held on it by the screw Q2. It is ixed against turning on extension 2l by a pin 36. Cam 33 thus turns with valve member l0. Attached to front piece 26 is a pin 37 which rests on cam 33 and is held in oontact with it by the weight ot.' the gas burner.

lWith the above described arrangement, it will be seen that when the valve is closed, this being the position ot the valve when handle l1 is parallel to the gas supply pipe 7, the cam is in a position to hold the burner in the highest position and that as the valve is then opened the cam will be moved to permit the burner to lower gradually. The parts are so proportioned as to give the desired rate of adjustment for the different valve openings so that the burner will be correctly positioned for heating most eliticiently. Cam 33 can be made of suitable pitch to meet t-he conditions of any service require-ment. Thus `as the burner is turned on and oli.1 it will be at the same time automatically adjusted with relation to the utensil being heated. Ihen the burner is adjusted it moves on nozzle as a YFulcrum, the opening 1G being large enough to permit ot' the necessary turning movement. At the same time support Q4 moves on fixed support 29 as a fulcrum, support 24 being in substance a lever pivotally mounted on support 29. The entire weight of the burner is carried by the support or trame and this weight is transmitted to valve member 10 through pin 37 and cam 33. The weight of the burner thus serves to hold valve member 10 on its seat in valve body 9. This is an important point in connection with my invention for by they arrangement I malte the burner itself perform the function of the spring usually provided on the valve.

Preferably I make cam 33 of a length less than the total throw of valve 8 so thatl thi` valve can be adjusted somewhat after the burner reaches either its highest or its lowest position. To this end, cam 33 merges into flat portions 3S and 39 at its two extremities along which portions pin 3T moves after it leaves the surface ot' the cam, to permit of regulation of the valve after the valve is in either of its extreme positions. The valve may have the usual movement ot 90 degrees between fully closed and fully open position, the flat. portions 3S and 39 being' arranged at the two extremities ot this 90 degree movement. Preferably, however, I position the stop which limits the opening movement ot the valve slightly more than degrees from the other stop so that after the valve has been fully opened it can be moved still further to shut ott' somewhat the valve. In other words, the valve can be moved beyond the position in which opening l2 is in line with the passages in nipples 13 and 14, so that after being fully opened the valve can be shut oft again to a limited extent by moving the valve handle still further in the opening direction. Also in valve member l() I provide notches 50 which are in line with the openings l2 and form in substance circumferential extensions of such openings. This serves to eiiect al very gradual opening and closing ot the valve.

lVith this arrangement, when the valve is' tully closed pin 37 rests on the flat snr'tace 3S, the burner being held in its highest position. Now when it is desired to use the burner, it can be opened or turned on to a limited extent be'lore the burner will start to lower, so that in this initial position the iiame can be regulated to a certain extent. As the flame is turned on beyond this limited extent. the burner will be gradually lowered until it reaches its lowest position, in which position the gas will be fully on, pin 37 now resting ou the [iat portion 39. It now the tlame is too high, then the valve can be turned still further to shut it oili somewhat. pin 37 moving along the :flat surface The valve can be turned ott' until pin 19 strikes the opening stop 20.

Then it is desired to adjust the initial setting of the burner, this can be done readily by bending the side arms 25 of the snpporting trame 94 at the point indicated at 40.

An important advantage possessed by my invention is that it can be provided at a low cost. and can be applied easily to a gas stove with but little change; and such changes as are required are ot a simple nature. The cani 33 can be applied to the stove by merely removing the screw 22, discarding the spring ordinarily provided, and replacing `it by the cam 33. The frame can be made out o't suitable metal and is easily applied to the stove and burner. In this connection. it will be understood that the Li (l iteaeea particular 'trame structure illustrated is only by vvayvot sample and 'that it may taire to meet any particular' con sith. rllhe essential thing' is ditions niet v that the burner be mounted on the trame or support, and that it. in turn be suitably mounted so as to be raised and lowered by the cam.

In Figs. t3, and T I have illustrated a moditied iorin ot my invention wherein 'the valve is shown as beine' horiz mtal instead ot vertical. the cam in this case tartine' the form ot' a cylindrical surface. In these figures the saine rete 'ence numerals vvith the expo nent /z added are used to designate corresporuilinn` parts.

Referring particularly `to Fin'. 7, 'the space between the tivo lines A and B represents the active portion ot the cam which serves to raise and lower the burner. ivhile the portions between the lines A and D, and between the lines P and C are concentric with the center ot the valve and permit movenient of the valve without moving' the burner. In other Words, these portions are in the nature ot guiding' surfaces. In this arrangement a spring' lll is provided to hold the valve on its seat, the valve beine' horizontal.

The operation of the arrangei'nent shown in Figs. 5 to 'T is similar to that oic the arraiigement shown in F igs. l to 4t and will be readily understood 'from the description already given in connection ivith Figs. l to l.

In accordance with the provisions oit the patent statutes, I have described the principle of operation of my invention, together with apparatus 'which I now consider to rep-l resentthe best enil'iodin'ients thereof; but I desire to have it understood that the constructions shoivn are only illustrative and that the invention can be carried out by other means.
